VENEER CASK.

SPIEGlFIGATION forming part of Letters Patent No. 626,248, dated June 6, 1899.

Application filed March 15,1898. Serial No. 673,980. (No model.)

To (LZZ whom, it may concern:

Beit known that I, GEORGE SAUTER, joinermaster, a subject of the Emperor of Germany, residing at Charlottenbu rg, near l3e1'lin,in the Province of Brandenburg and Empire of Germany, have invented certain new and useful Improvements in Veneer Casks; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

For the transportation of beer and in general of liquids producedand stored under pressure veneer casks could not hitherto be generally used, since, in the first place, the heads and casings of the casks do not offer sufficient resistance to the great pressure, and, in the second place, the beer does not remain suificiently cool in such casks and the stored liquor is spoiled by the influence of the All these difficulties are avoided by bending the projecting ends of the cask against the heads and gluing them to same, so that these lapping portions hold on the heads, and by inclosing the cask with an air-tight casing, so that the inner caskbody is surrounded by a layer of air, room for receiving carbonic acid, &c., is provided, and aflnid under pressure may be introduced between the inner and outer cask-bodies.

Such a cask is represented in longitudinal section in Figure 1. Fig. 2 is a similar view of the cask-body before the laps are bent down. Fig. 3 shows the head, and Fig. 4 a finished cask without the casing. Fig. 5 shows the staves of which the casin g consists. Fig. 6 is an inner side view of the casinghead. Fig. 7 is an outside view of the caskbody head, showing the downturned laps.

The inner casing of the cask consists of the veneer sheet a, which is sharpened at oppo site ends and glued together to form a cylinder. The sheet a is aveneer, with its grain in the direction of the length of the cask and of a thickness of three millimeters to ten millimeters, according to the requirements of the liquid. \Vith casks for vinegar, must, overfermented beer, and the like the inner casing must, for example, be made thicker than for casks for underfermented beer, since for the first the tannic acid of the oak wood is necessary for the preservation of theliquid,

while in the latter case the cask can be glazed. On the ends of this casing are placed the rabbeted heads A which are made of veneer plates glued together, with intervening layers of cloth, or such heads may consist of a layer of thick veneer ora single wooden piece, being arranged, however, in any case so that the flange 0 thereof just covers the end of the caskcylinder A. The places where the heads A meet the casingaare rounded oiflas shown. On the completely closed hollow cask so formed are glued, one after the other, several layers of veneer e e alternately with layers of fabric f, of suitable material, such as linen, in such manner that successive layers break joint. Moreover, these veneer layers are made somewhat wider than the length of the cask to be made, so that they project somewh at beyond the heads. The projecting ends are out or notched, so that the laps g are formed as shown in Fig. 7. The laps g are then bent over and held against the beads by means of clamping devices. The laps g are warmed, so that they become flexible and may be pressed against the heads A In the above manner I produce a cask as shown in Fig. 4.

It is not necessary that the projecting ends should be notched, as a single impervious membrane may be used, which may be suitably folded over and the ends pressed against the heads.

For the formation of the outer easin g veneer bands F F are first wound around the cask shown in Fig. 4 in the manner indicated in Fig. 1.

If barre1-shaped casks are desired, it is only necessary to make the middle band thicker than the end bands. \Vhen all three bands are wound around, the outer casing-cylinder is glued to same.

The heads A of the casks are provided with supporting-plates B on which the second or outer heads a rest, the space between these plates and the downturned laps g being occupied by blocks D. The cask-body a a has also at the center and at the ends veneer bands F F, rolled around the same. The

outer casing V. The cask proper is thus always surrounded by a layer of air, which regulates. and maintains uniform the temperature in the inside of the cask. The outer Walls and the outer casin g are provided with air-holes 1. Cold air ora fluid-pressure agent, such ascompressed air, can beiintroduced through these openings from any suitable source, so that a counter-pressure is exerted inwardly on the inner cask, which balances the pressure of the fermenting liquid on the inside, which conduces to the durability of the cask proper, as the latter has to sustain no pressure; or the space between the outer and inner casings can be filled with carbonicacid gas, so that a transportablecask with a carbonic-acid receptacle is provided. Such a cask is of value in that it enables the sale of beer in the keg for household purposes.

The outer casing V can consist of separate rabbeted staves 10 Fig. 5, that overlap one another to permit such movements of the end bands F forming at their outer edges the chimes of the cask, and aspace being left between 'the cask-body and outer casing suitable for the reception of carbonic acid or fluidpressure agent.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE SAUTER.
